The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Openworked (ref. 26735SG.OO.1320SG.01) merges bold innovation with the maison’s most recognisable silhouette. Introduced in 2024, this 41mm limited-edition blends architectural transparency with material novelty, rendered for the first time in 18-carat Sand Gold – a proprietary alloy positioned tonally between white and pink gold.

Its case, bezel, and integrated bracelet in satin-brushed and polished Sand Gold frame a dramatic openworked dial, revealing the intricacies of calibre 2950. This self-winding movement offers 65 hours of power reserve and places a flying tourbillon at 6 o’clock beneath a smoked sapphire crystal. Open bridges and skeletonised components reveal the calibre’s structure without compromising rigidity or performance. Water-resistance is rated to 50m – sufficient for daily wear but clearly engineered for fascination rather than utility.

Marked by its technical prowess and the premiere of a new gold alloy, this reference asserts Audemars Piguet’s contemporary relevance in high complication watchmaking. Its limited production and departure from traditional case materials position it as both an aesthetic exploration and a collector milestone within the Royal Oak evolution.
